Description: Long twist drill bit, covered in a thin layer of rust.

Drill bits are cutting tools used to create cylindrical holes. Bits are held in a tool called a drill, which rotates them and provides axial force to create the hole. The twist drill bit is the type produced in largest quantity today. It drills holes in metal, plastic, and wood. The twist drill bit was invented by Steven A. Morse of East Bridgewater, Massachusetts in 1861. He received U.S. Patent 38,119 for his invention on April 7, 1863.
